Last month I wrote about Austria Solar’s annual report, whose pages became visible only when exposed to sunlight.
Now Buenos Aires based bookshop and publisher Eternal Cadencia has released ‘El libro que no puede esperar’ i.e. ‘The book that cannot wait’ – an anthology of new fiction printed in ink that disappears after two months of opening the book!
How is that possible? Well the books are silk-screened using a special ink and then sealed in an air-tight packaging that once opened allows the printed material to react with the atmosphere. The result being that after two months, the text vanishes.
In the age of portable electronic readers and e-books, I think this a magical way of adding an element of urgency to reading while motivating readers, promoting authors and at the same time benefiting physical book publishers.
